This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic...(View More) fields in nature. This activity requires use of a galvanometer, bar or cow magnet, and wire. This is the fifth lesson in the second session of the Exploring Magnetism teacher guide.(View Less)

Learners design, build, and improve a model that mimics gravity-assisted space travel. The design solution enables a steel ball (spacecraft) to roll past a magnet (force exerted by a planet), which will alter its direction in order to hit a...(View More) designated target (e.g., Mars). Includes challenge video, leader notes, and handouts. Two supplemental videos are included: 1) gravity assisted travel used by NASA's New Horizons mission and 2) NASA aerospace engineer Victoria Garcia describes how she uses virtual-reality tools to design living and work spaces for astronauts. She also talks about not letting her deafness be a barrier in her life. This challenge is part of Mission: Solar System, NASA and Design Squad® Nation, a series of hands-on activities and videos let kids apply science, technology, engineering, and math (STEM) skills to solve design challenges. Introductory resources include resources for running a challenge, introducing the design process, and tips for facilitating open-ended challenges.(View Less)

Learners design and build a device that can pass above a surface and detect magnetic fields. The video shows kids using the engineering design process, applying a variety of science concepts (e.g., force, magnetic fields, mapping), and learning...(View More) about how a planet's or moon's magnetic field gives NASA scientists insights into its structure and how it formed. Includes challenge video, leader notes, and handouts. Two supplemental videos are included: 1) Measuring Magnetic Fields and 2) NASA flight systems engineer Tracy Drain explains her role on the Juno spacecraft team. This challenge is part of Mission: Solar System, NASA and Design Squad® Nation, a series of hands-on activities and videos let kids apply science, technology, engineering, and math (STEM) skills to solve design challenges.
